DigiTune GTS

Tune smarter with log-based VE analysis.

Buy a GTS licence

DigiTune GTS turns engine data logs into accurate, actionable VE plots — letting you tune fuel, ignition, boost and knock with precision that real-time tuning can’t reach. Currently in open beta.

Log-based VE tuning

Intelligent data processing maps every log datapoint to its row and column in the VE table, with full RPM/load compensation. Drag points on the graph, type values, or nudge with hotkeys.

Resonance-aware columns

Plot volumetric efficiency against RPM and align your table columns with the engine’s natural resonant peaks and troughs — something live tuning simply can’t see.

Knock threshold tuning

Raw knock sensor signal vs RPM with the ECU’s Background Noise and Acceptable Level overlaid. Dial in optimal knock detection without false triggers.

Ignition timing

Use knock data to refine your timing tables based on what actually happened — not on relying on real-time ECU correction.

Idle & boost control

Calculated plots from logged data drive your idle and boost duty cycles. Replace trial-and-error with measurement.

Temperature compensation

Load warmup sessions or multiple logs from different conditions — GTS helps you account for intake air and coolant temperature effects across the whole map.
